Medical Imaging

Active contour models, commonly known as snakes, have been widely used for object localisation, shape recovery, and visual tracking due to their natural handling of shape variations. The introduction of the Level Set method into snakes has greatly enhanced their potential in real world applications. For more information, see our active contours website.

Pharmacological MRI

Working in collaboration with the Psychopharmacology Unit, we are investigating and developing exploratory, data-driven methods for the analysis of pharmacological MRI (phMRI).

The data produced in these studies can be thought of as 3D movies of the brain, where we seek to discover both the temporal and spatial effects of a drug, especially in cases where the expected neural response is not well established.
